-The experiment will introduce different level of precision and measuring to the appropriate decimal place and will be familiar with measurements and weight.

2. Write the symbols and equation used to make a dilute solution from concentrated or stock solution. - The concentration of substance is described as molarity and this can be expressed as – Molarity = moles of substance per liter of solution.

4. Write the relation between Kelvin and Celsius scale, and Fahrenheit and Celsius scale. -The Kelvin and Celsius scale are the same both are one hundred of between freezing point of water and boiling point at standard atmospheric pressure.

-Fahrenheit and Celsius scale it is an interval of 180 to cover the same range as 100 Celsius. The degree Fahrenheit is only 100/180 as large as degree Celsius.

5. What is a meniscus? Which level of meniscus would you record to get the correct volume of water from measuring devices?

-Meniscus is a measurement used for measuring liquids, for water and most liquids the line with the center of the meniscus reading in the bottom is used.

6. How would you clean the lab after completion?
- Items in labpaq are generally used multiple times. Always clean and return un used items to the bag after completing experiment.
-Clean used and left over chemicals with paper and place in a garbage or flush down using enough amount of water.
-To clean from graduate cylinder pour the solution and clean with water several times.
-Use a liquid dish washing detergent with worm water.
-use soft cloth or to clean residue from the surface.
-Dry test graduate cylinder by placing them upside down in the test tube or using paper towel.

Effects of Temperature on Enzymatic Activity
Abstract
Temperature is a measure of kinetic energy. As this movement increases, collision rate and intensity, and therefore reaction rates, increase. This experiment was conducted to determine if there is a minimum temperature that increase kinetic energy and denature enzymes to slow enzymatic reactions or fail to catalyze them. The experimental results indicate...

Lab 5: IonicReactions
Submitted by
Abstract:
The purpose of this experiment is to work with aqueous solutions of ionic substances. Aqueous solutions are those solutions in which water is the solvent. When ionic substances are dissolved in water, the ions separate and become surrounded by water molecules. The focus of this experiment is on precipitates. The goal of this experiment is to study the nature...

Title: Experiment #8: IonicReactions
Purpose:
In this lab we will work with aqueous solutions of ionic substances and determine if they are soluble. If the solution appears milky than it is known as a precipitate reaction, meaning it is soluble, and that the ions separated and became surrounded by water....

Is H20 Bad for You?
Abstract:
In the village of Gopher Hollow there’s a cluster of Blue Baby Syndrome. There were
four infants affected by this cluster. The families from the infants would collect their
water from wells. We have to determine what’s the source of the high levels of nitrites in
the water. The four sources that could be the point of contamination are a new
subdivision, textile plant, an organic farm,...

...living cells that catalyze (increase the rate of) chemical reactions. The molecule in an enzyme upon which the enzyme act is the substrate, which binds reversibly to the active site of the enzyme. The active site is the part of the enzyme where substrate binds. The result of this union (enzyme – substrate complex) is a redistribution of chemical energy required to activate the reaction of a substrate molecule to form products. The optimum reaction...
